    cylinder lock
    The invention relates to a lock cylinder with a cylinder core which can be rotated in a lock cylinder module and a locking lock for blocking when the lock cylinder module is opened or closed.
    Lock cylinder with a lock cylinder module, in which a rotatable and lockable cylinder core is located, are known from the prior art. An essential security problem of such locking cylinder is that the lock cylinder can not be exactly adapted to the thickness of the door to be locked in the rule, but protrudes a few millimeters to centimeters from the plane of the door. By applying a suitable breaking tool, the lock cylinder can be broken off from the outside and the cylinder core can be actuated. As a remedy, it is known to attach safety fittings in the form of cuffs or the like on the outside of the castle to make the attachment of the breaking tool impossible. However, such security fittings are expensive and must be adapted to the length of the cylinder.
    As a remedy to this problem, it is known from DE 200 21 352 U1 to provide a Sicherungszuhaltung for blocking the cylinder core, which is activated in combination with a predetermined breaking point in the cylinder housing when breaking the cylinder housing and blocks the rotation of the cylinder core. According to the prior art, this Sicherungszuhaltung is provided in the cylinder housing and includes a locking bolt, the immediately adjacent and axially or offset from the housing or. Core pins of the cylinder lock is arranged. A predetermined breaking point in the cylinder housing ensures that when an external force acts on the housing, it breaks at a defined location and the shear lock is activated. 2/21 • · • · • ···

    A problem of this prior art device is that the cylinder housing must be designed to receive the locking latch. This means in practice that produced for the widest variety of dimensions of the cylinder housing versions with and without Sicherungszuhaltung and kept in stock. This means an increased logistical and production-technical effort. In addition, the cylinder housing is unnecessarily weakened by the additional holes and recesses for receiving the Sicherungszuhaltung, which is ultimately detrimental to the security of the castle.
    The object of the present invention is to remedy the disadvantages of the known devices and to realize a cylinder lock with safety lock, which is easy to manufacture and can be modularly combined with other existing cylinder locks, without compromising the degree of security against break-open attempts to have to.
    This object is achieved according to the invention in that the securing tumbler is arranged in a scanning unit adjacent to the lock cylinder module and for scanning the position of the lock cylinder module comprises a scanning pin and a locking bolt for blocking.
    By virtue of the fact that the locking tumbler is located-preferably in its entirety-in a separate scanning unit, in principle any compatible cylinder lock can be equipped with a corresponding securing lock. The presence or absence of the lock cylinder module (typically the outboard portion of the cylinder housing) is detected directly by a sensing pin, which in turn causes blockage of the cylinder core in the absence of the housing member.
    According to the invention, it can be provided that the securing tumbler is designed to block a core extension provided adjacent to the cylinder core. This has the advantage that housing and Kernstiftanordnung in the housing parts or in the cylinder core need not be changed, as well as the blocking element for bucking not in the cylinder core, but in a separate part, just the core extension, engages. 3/21 ··· ·· ···· ··· # ···· «····· ········································································ ··· ·· ·· ··· ·· ·· ··· ·

    The lock cylinder module may comprise a housing part, and the scanning unit may comprise a retaining housing receiving housing. In this case, the housing part can be carried out in a known manner. Conventional housing extensions can be easily adapted to accommodate the locking tumbler. The core extension may comprise a coupling extension in a known manner.
    According to the invention may further be provided that the sensing pin is mounted so movably in a bore of the housing extension that it is adjacent in the mounted state at one end to the lock cylinder module and engages at another end in the movably mounted, spring-loaded locking bolt. As a result, the sensing pin can serve as a detector for canceling or removing the lock cylinder module. Preferably, it can be provided that the locking bolt has a constriction region, which corresponds with an end cap of the scanning pin such that the spring-loaded locking bolt is released upon movement of the scanning pin in the bore. However, the locking bolt can also be connected in a different way to the scanning pin, it merely has to be ensured that, when the lock cylinder module is removed, the scanning pin releases the locking bolt.
    The locking bolt may preferably have an end cap, which is executed upon release of the locking bolt for engagement in a counterbore of a core extension connected or connectable with the cylinder core. As a result, the locking bolt lock the core extension. Such a core extension may preferably be rotatably mounted in the housing extension. An actuation of the cylinder core by turning the core extension from the outside is made impossible by the locking bolt.
    The housing part as part of the lock cylinder module and the housing extension may preferably be mounted on a common axis or be attachable, wherein the axis has a, their mechanical strength-reducing, predetermined breaking point, preferably in the form of a constriction. The breaking point can be vorzusweise realized in the form of an annular groove. 4/21

    When trying to cancel the outer housing or lock cylinder module breaks not the housing, but firmly connected to the housing axis, and the housing is not damaged, but falls off with the broken axis of the lock. This is also advantageous insofar as it is simpler in terms of production technology to provide a rotating part such as the axle with a predetermined breaking point, as a complex component such as the housing itself, which must serve for firmly holding the cylinder core. The housing parts can be firmly connected by screw and / or positive connections with the axis.
    The sensing pin may further include a reduced diameter sensing nose for sensing the position of the locking cylinder module at one end thereof. Preferably, the sensing pin is slidably mounted in the interior of the housing extension in a bore whose axis is substantially parallel to the axis of the cylinder lock. The bore may preferably be made with stepped diameters to prevent the sensing pin from being removed from outside the bore.
    The locking bolt may have a locking head with an end cap for engagement in a counterbore of a core extension and a central part, wherein the locking head has a larger diameter than the central part whereby an edge is formed between the locking head and middle part. The fact that the locking bolt engages in the core extension, and not in the core itself, has the advantage that the construction can be easily retrofitted to existing locks.
    The edge between locking head and middle part, which is usually realized in the form of a jump in the diameter of 0.05 to 0.2, preferably 0.1 mm, serves to ensure that the locking bolt in the snapped (blocked) state not by applying the impact method the core extension can be removed. As soon as the locking bolt is inserted into the core extension and the core extension is twisted from the outside, the locking bolt remains attached to the edge, and knocking out of the core extension is impossible. 5/21 • · «« ··· «« ···················· 51479 Ag / Fl

    According to the invention, it can be provided that the core extension has a plurality of countersunk bores on the circumference for receiving the locking bolt. This facilitates assembly, since the core extension can be used in any position.
    It may further be provided that the housing extension is positively connected via a rectangular recess and with an additional locking pin with the axis. Furthermore, the axis bores for connection to the housing parts and the housing extension and in a known manner have a forend screw hole.
    Serving as a predetermined breaking point constriction of the axis may preferably be formed as a circumferential annular groove and arranged in the transition region between the housing extension and the second housing part such that in the assembled state, an external force is discharged to the second housing part directly on the annular groove. This ensures that the axis breaks, not the case or core.
    Further features of the invention will become apparent from the claims, the description and the drawings.
    The invention will be explained in more detail below with reference to an exemplary embodiment according to the invention. Show it

    Fig. 1 shows an exploded view of a lock cylinder according to the invention. The lock cylinder 1 comprises an axle 5 on which a first housing part 2a and a second housing part 2b are mounted. For this purpose, the axis 5 is provided with holes 17, in the screws 16 for fixing the housing parts 2a, 2b are inserted. The axis 5 further has a forend screw hole 6 for fixing the lock cylinder in Einstemmschloss. The housing part 2b carries a cylinder core 3 and forms with it the lock cylinder module 27.
    Directly adjacent to the bore 17 and thus close to the end region of the second housing part 2b, the axis 5 has a constriction 8, which serves as a predetermined breaking point and is designed as a circumferential annular groove shallow depth. The depth of the annular groove is chosen so that on the one hand, the axis remains stable enough to withstand conventional loads, but when attempting to break the housing, safely forms a break point.
    The axis 5 further has flats 14 which form a rectangular shape, which serve for the positive reception of a housing extension 7. For this purpose, the housing extension 7 has a corresponding corresponding recess 22, and a bore 19 for receiving a locking pin 18, wherein in the axis 5, an aligned bore 15 is provided.
    The housing parts 2a and 2b accommodate cylinder cores 3, which can be coupled or coupled to a locking bit 4. In the cylinder cores 3 and the housing parts 2a, 2b are in a known manner housing pins and core pins (not shown) for locking the cylinder lock.
    Between cam 4 and lock cylinder module 27, a scanning unit 34 is inserted, which comprises a housing extension 7. The housing extension 7 is provided between the two housing parts 2a and 2b and receives a core extension 11, which couples the two cylinder cores via core engaging projections 24 with the lock bit or each other. For this purpose, a coupling extension 13 is inserted into the core extension 11. 7/21 ······ · · · · · · · · ··················································································· · · 7 51479 Ag / Fl

    Such housing extensions for adapting the cylinder lock to the thickness of a door leaf are known in principle from the prior art.
    In the lower region of the housing extension 7, the actual retaining tumbler 12 is provided, comprising a locking bolt 20, a compression spring 21 and a scanning pin 10.
    The scanning pin 10 is movably mounted in a substantially aligned parallel to the axis 5 bore 23 and can detect the presence or absence of the second housing part 2b through a sampling opening 23. At its other end the scanning pin 10 engages in a constriction region 26 of the locking bolt 20, which is held under spring tension of the compression spring 21 in a bore which is provided substantially radially to the axis 5 in the housing extension 7. As soon as the scanning pin 10 leaves its position, the locking bolt 20 is released and engages at its upper end in a counterbore 25 on the outer circumference of the core extension 11. As a result, the movement of the core extension 11 is blocked.
    2a shows a schematic view of an embodiment of a lock cylinder 1 according to the invention. The lock cylinder 1 is designed as a double cylinder and has a first housing part 2a and a second housing part 2b, which are attached to a common axis 5. In between is the cam 4 and the scanning unit 34, which detects the presence of the lock cylinder module 27 and includes a housing extension 7. The axis 5 carries in a known way, the cuff screw hole 6 for fixing the cylinder lock in Einstemmschloss and has a constriction 8, which serves as a predetermined breaking point.
    In the interior of the housing parts 2a, 3b cylinder cores 3 are provided, which are coupled via a core extension 11 (not shown) with each other. A key 9 is inserted into a closing channel of the cylinder core 2 and actuates the cylinder core and in consequence the cam to lock the cylinder lock. 8/21 8

    Fig. 2b shows the cylinder lock of Fig. 1a in the broken state. By applying a suitable burglary tool was trying to cancel the lock cylinder module 27 in the form of the outer second housing part 2b, in order to get access to the cylinder core or the cylinder core extension in succession, and to operate the lock bit. Instead of the housing, however, the axis 5 is broken at the constriction 8 and releases the scanning pin 10 of the scanning unit 34. The retaining tumbler is activated and the locking bolt 20 blocks any movement of the core extension 11.
    Fig. 3a shows the cylinder lock of Fig. 1a in cross section. In this view, it can be seen that the housing extension 7 includes a core extension 11 adjacent to a safety cage 12. Fig. 3b shows the cylinder lock on Fig. 1b in cross section. When the second housing part 2b is broken away, the sensing pin 10 releases a locking bolt 20 biased by a compression spring in the housing extension 7 upwardly into a counterbore of the core extension 11, thereby locking it against rotation.
    Fig. 4a shows the securing tumbler 12 in detail in the assembled and non-blocking state. The locking pin 20 is held at its lower end (the spring holder 33) by a compression spring 21 and pushed upwards.
    This pressure is counteracted by the follower pin 10, which has a dome 29 at one end, which engages in a constriction region 26 of the locking bolt 20 and holds the locking bolt 20 in position. At its other end, the scanning pin 10 has a Abtastnase 30, which has a smaller diameter than the Abtaststift 10.
    In the present embodiment, the Abtaststift 10 has a diameter of 3mm +/- 0.02mm and the Abtastnase 30 has a diameter of 2mm +/- 0.02mm. Adjacent to the constriction region 26, the locking bolt 20 has a central part 32, which is designed with a diameter slightly smaller than the rest of the locking bolt 20. In the present example, the middle part 32 has a diameter of 3 mm +/- 0.05 mm, while the spring holder 33 has a diameter of 3.1 mm +/- 0.02 mm. ••••• · · · • · · · · · · · · · • · · · · · · I ····· ♦ · · · · · · · · · · · · · · · · 9 51479 Ag / Fl

    The constriction 26 is designed with a diameter of 2mm +/- 0.02mm. The free end of the locking bolt 20 is designed as a locking head 28 having a slightly higher diameter, so that a step 31 is formed. In the present embodiment, the diameter of the locking head is 3.1 mm +/- 0.02 mm, thus the height of the rotating step is about 0.05 mm. Like the sensing pin 10, the locking pin 20 is also formed at its end with a dome 29 to ensure a smooth engagement in the counterbores of the core extension. The crests are preferably embodied at an angle of approximately 60 ° to the longitudinal axis of the scanning pin 10 or locking bolt 20.
    Fig. 4b shows the locking circlip in the blocking state: The sensing pin 10 has moved axially outward and released the locking pin, whereby this is pressed by the compression spring 21 upwards and engages with its locking head 28 in the counterbore 25 of Kernveriängerung.
    The invention extends not only to the exemplified embodiments, but also includes other embodiments within the scope of the claims. In particular, the invention is not limited to the specifically described embodiment of the Sicherungszuhaltung. 10/21
